HEAT-RADIATOR.

' Specification of l miters Patent. Application men may a, 191?. sedan no. 699,430;

To all whom it may concemi- 4 ;Be.it lmewnthat I, Aiivr'N BeNEIfiAN, a citizen of the United States, residing at the borough of the Bronx, city, county, and State of New York, have invented certain new and useful Improvements in -eat- Eadiators, of which the following is a specification.

lily improvements relate to the class of radiators for heating, either y means of steam or hot water", in w ich a continuous coilof thin copper tubing is used in conjunction With transverse radiation plates forced thereon so as to attain intimate contact therewith and thereby facilitate the rapid difiusion of heat. Heretofore these radiation plates have been made in the form of individual disks each with asin le hub tioned and arranged as'to e to concentrate is emaximum 0 flange for contacting with. asingle orizontal member ofthe copper coil.

A distinguishing feature of my present i nvention consists in the provision of a series of transverse radiation plates made of thin sheet metal, each plate being common to; and contacting with each of the horizontal members of the copper coil, whereby a series of vertical air channels is constituted through which the air .is positively conducted from the bottom to the top of the radiator in such manneras to insure the absorbing by the air of a high degree of heat by convection. By this means I am enabled radiation surface within the minimum of space. That is to say, the radiation plates are so properectually take up and disseminate the maximum of heatthat can he impart to and hgthe copper-coil, while at the same time a lintermed-iate or lost space inthe area ofradiation-isavoided,

each radiation plate being continuous. for the wholeseries ihorizontsimembers of the coil, which latter mayth'us be arranged nearer toget e rdativelyspeaking,sq as to reduce the..height',of the radiator without crowding. it .or. reducing"; efiieien'cy.

My new construction ef-rsdisuonzz iate obviates wastegof metaljnfmanufacture as compared with the multiple d sk system of radiation plates heretofore. used .ndhi1ee mmdiator of pi'escri'bed .eapaeuyrney made caper, as we'll ejjrigiie. hot structure. urthermore. th s strue iii-e s on e m s w nesses rw fzheehs; at suitable dies,

Another advanta e is that the rigidfl-hte- I .gral structure thus attained enables, fne to dispense with the independent coil standards heretofore used, rovided with rests or bearings for each horizontal member of the coil, and in lieu thereof to support theradiator as a unit upon the feet secured directly to and between adjoining radiator plates in such manner that variations in floor level may be com pausing wit the heavy casti'ron' standard 'er'etofore used, the gifoss weight of the radiator, consideredas" a whole, is still further reduced,,the result being a light, compact, rigid, portable structure of maximum iiig capacity, which may be conveniently and safely transported, handled and manipuand requirements of actual use. U Inthe accompanying drawings, Figure. 1, is a side elevation of a radiator unit, broken away centrally, formed in accordance with upon plane of line 5 5 Fig. 4]; Fig. 6, a

' lated, and adapted to the varying conditions,

per tubing oi u'niform diameter throughout, 7

the horizontal members a, being connected by semi-circular coupling members 0, whic are attached thereto after the radiation plates p, have been forced on said horizontal ncouplinig members a, to the horizontal members 0, being efie'cted' y brazing or ei'wise uniting the-edges of the piping.

he radiation plates 0, are formed of comfieithrelyv thin sheet metal, stamped out by with flanged openthe attachment of the semiEcircuings p, for the horizontal members 0, of the co1l,'-the flanges p being forced into intimate contact with the copper tubing when said horizontal members 0, are inserted in the openings p, so as to insure perfect conductivity between the parts.

. Each radiation plate 1;, thus contacts with each horizontal member 0, of the coil C,the series of radiation plates thus binding and uniting the parts into a rigid, integral structure, and positively spacing and reinforcing the coil so that its members cannot be bent or twisted with relation to each other, at the same time preserving the relation and alinement of the radiation plates themselves.

The width of the radiation plates p, and their area between the flanged openings 72, is proportionate .to the cross section and heating capacity of the coil, so as to afford into intimate relationand contact with the opposed surfaces of adjacent plates, and within the area of influence of each longitudinal member 0, of the coil, thereby quickly imparting to the air a relatively high degree of heat and insuring a rapid diffusion thereof into the atmosphere above and around the radiator.

The coil C, and its radiation plates 19, constitute a unit which is essentially selfsupporting, and may be so used if desired but in order to facilitate access of air to the bottom of the radiator, to aiford a broader floor bearing, and to compensate for inequalities of floor surface, I prefer to use two or morefoot pieces 1, f, clamped to and between the lower ends of adjacent radiator plates p, as shown in the last four figures of the. drawings. The lower portion of each foot piece is shown as bifurcated to attain a suitable spread or protrusion beyond the width of the radiation plates p,

with lightness of structure. llhe upper portion is also bifurcated to form bearing arms 1, 1, between which is a semi-circular seat 2, the radius of which is greater than that of the portion of the. coil resting thereon, as shown in Fig. 4. The thickness of the upper portion ofthe 'foot piece f, is equal to the space between the opposed faces of ad- 5 and 6. In thisposition it is secured by upon the foot pieces fi one of which -is joining radiation plates, so as to fit snugly etween and 'thereagainst as shown in' Figs.

ing through slots p, in the lower ends of the radiation plates 79, and through a hole 3, in the foot piece f, said hole 3, being of greater diameter than the diameter ofthe bolt 6, as will be seen by reference to Figs. 4: and 5. The slots p in the lower ends of the radiation plates between which the foot pieces are inserted, are of practically the same width 'as the diameter of the bolt Z2, and are open at their lower ends so as to straddle the bolt 6, as shown in Fig. 7. The hole 3, in the foot piece f, of greater diameter than the bolt 6, affords a margin for adjustment between the parts. Thus it being understood that the lower horizontal member of the coil rests on the semi-circular seat 2, which is eccentric as related to said horizontal member 0, it is obvious that the margin of adjustment afforded by the hole .3, will admit of the placing of the foot piece f, to compensate for any slight variation from the horizontal in the floor support while eflecting the true vertical alinement of the radiation plates andcoil as a unit provided at each end ofthe radiator It will thus be seen that the coil is supported upon and by the radiation plates in lieu of the old method of supporting the coil directly upon heavy uprights, or standards; and that the latter are practically dispensed with since the foot pieces f, are mere at v tachnients to the lower extremities of the radiation plates at the ends of the radiator, and are comparatively small and light of weight. Furthermore they afl'ord COHVell'r ient means for effecting the vertical alinement of the radiator and compensating for inequality of floor support.

What I claim as my invention and desire to secure by Letters Patent is,

l. A radiator of the character designated comprising a coil of tubing of uniform diameter, and a series of sheet metal plates extending continuously from top to bottom of the coil, each formed with a series of hub flanges contacting with the horizontal members of the coil and forming therewith a rigid integral radiator, unit,'the end plates extending beyond the lowermost horizontal '-member of the coil and forming a means for supporting the coil.

2. The combination with a radiator having a cylindrical member, of a support therefor having a semi-circular seat to receive said member, said radiator having dependin flanges embracing said support and secure thereto.-

3. In combination with a radiator having a lower cylindrical member and depending flanges, foot pieces fitting snugly between said flanges, each being formed with a semicircular seat for said lower cylindrical member, said seat being of greater radius than that of the cross section of said cylindrical 130 membef, ea h feat iece being also formed the aid radiawr innit a ttained, as\ and for wglith i-belt hole 0 glraater diameter than thepurpase set Earth.
